Description

Technical Field

[0001] This utility model relates to the field of dehumidification tunnel furnace conveying technology, specifically to a reel circulating conveying mechanism. Background Technology

[0002] A hot air circulating tunnel oven is a heating device mainly used for heating, drying, and dehumidifying products or materials. It consists of a furnace body, a hot air generating component mounted on the furnace body, a hot air circulation channel inside the furnace body, and a conveyor belt. The hot air generating component is connected to the hot air circulation channel. Products or materials are conveyed one by one into the furnace body via the conveyor belt for drying and dehumidification. In practical applications, this type of hot air circulating tunnel oven uses a conveyor belt to transport LED packaging reels or other sheet products into the furnace body for heating, drying, and dehumidification. Then, the conveyor belt directly transports the LED packaging reels or other sheet products to the next processing station for further processing. However, this conveyor belt not only has low conveying efficiency but also results in uneven heating of the LED packaging reels or other sheet products, leading to poor drying effects. This, in turn, prolongs the drying and dehumidification time, reduces drying efficiency, and also results in excessively long conveyor lines, increasing the overall footprint of the equipment.

[0003] Therefore, the applicant hereby proposes a reel circulation conveying mechanism to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reel circulation conveying mechanism.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model provides a reel circulation conveying mechanism, including a conveying component, a bidirectional conveying frame, and a stripping component; the upper and lower ends of the front end of the conveying component are respectively the input end and the output end, both of which are connected to an external conveying line; a plurality of bidirectional conveying frames are mounted on the conveying component; the conveying component drives the plurality of bidirectional conveying frames to perform cyclic conveying; and the stripping component is located below the output end of the conveying component.

[0007] Furthermore, the conveying assembly includes a transmission frame, transmission sprockets, transmission chains, and fixed plates; the side of the transmission frame is connected to the inner side corresponding to the tunnel furnace, and transmission sprockets are rotatably provided at both the front and rear ends of the transmission frame. Transmission chains are wound around the two transmission sprockets, and a number of fixed plates are equidistantly distributed along the transmission chain in its conveying direction. Each fixed plate is provided with a bidirectional conveying frame, and adjacent bidirectional conveying frames are in abutting contact with each other.

[0008] Furthermore, the bidirectional conveyor frame includes branch pipes, hooks, and a V-shaped limiting plate; two branch pipes are vertically fixed on the top surfaces of both ends of the limiting plate, and the rear sides of the non-fixed ends of the two branch pipes are provided with inwardly inclined hooks, and the bottom surface of the limiting plate is connected to the fixed plate.

[0009] Furthermore, the unloading assembly includes a mounting base and unloading plates. The mounting base is located below the output end of the conveying assembly, and the two unloading plates are located on both sides of the mounting base. The top surface of the unloading plates is constructed with an inverted V-shaped inclined surface.

[0010] Furthermore, the fixing plate has multiple convection holes evenly distributed along its length.

[0011] The beneficial effects achieved by this utility model are as follows:

[0012] The present invention provides a reel circulation conveying mechanism for loading and transporting LED packaging reels into a tunnel oven for circulating baking and dehumidification. Adjacent bidirectional conveyor frames on the conveying assembly cooperate to vertically load the LED packaging reels and automatically change the loading position of the LED packaging reels during the circulating conveying process in the oven. The reel can also be automatically unloaded by a unloading assembly. This not only improves the conveying efficiency but also ensures that the LED packaging reels are heated evenly on all four sides, resulting in excellent drying effect. This significantly shortens the drying and dehumidification time and improves the drying efficiency. At the same time, it avoids the problem of excessively long conveyor lines increasing the overall footprint of the equipment. Attached Figure Description

[0017] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0018] Example 1:

[0019] like Figure 1-4As shown, the present invention provides a reel circulation conveying mechanism for loading and transporting LED packaging reels or other sheet products into a tunnel oven for heating, drying, and dehumidification. The reel circulation conveying mechanism includes a conveying component 21, a bidirectional conveying frame 22, and a stripping component 23. The conveying component 21 is located inside the tunnel oven, with its upper and lower ends being the input and output ends, respectively, both of which are connected to an external conveying line. Several bidirectional conveying frames 22 are arranged on the conveying component 21. Specifically, several bidirectional conveying frames 22 are equidistantly arranged on the conveying component 21 along its conveying direction. The conveying component 21 drives the several bidirectional conveying frames 22 to perform cyclic conveying. The stripping component 23 is located below the output end of the conveying component 21.

[0020] The conveying assembly 21 includes a transmission frame 211, transmission sprockets 212, a transmission chain 213, and fixing plates 214. The transmission frame 211 is located inside the tunnel furnace, and its two sides are bolted to the corresponding inner sides of the tunnel furnace. Transmission sprockets 212 are rotatably mounted at both the front and rear ends of the transmission frame 211. A transmission chain 213 is wound around each of the two transmission sprockets 212. Several fixing plates 214 are bolted to the transmission chain 213 at equal intervals along its conveying direction. Each fixing plate 214 is bolted to... The bidirectional conveyor frame 22 is in contact with adjacent bidirectional conveyor frames 22; specifically, the transmission frame 211 has a transmission shaft rotatably mounted at both ends, and a transmission sprocket 212 is mounted on both ends of the two transmission shafts. A transmission chain 213 is mounted between the transmission sprockets 212 on the same end of the two transmission shafts. Multiple fixing plates 214 are bolted together laterally at equal intervals between the two transmission chains 213. The two ends of the multiple fixing plates 214 are bolted to the inner side of the corresponding transmission chain 213.

[0021] The fixed plate 214 has multiple convection holes 2141 evenly distributed along its length to increase the drying effect.

[0022] The bidirectional conveyor frame 22 includes branch pipes 221, hooks 222, and V-shaped limiting plates 223. Two branch pipes 221 are vertically fixed to the top surfaces of both ends of the limiting plate 223. The rear sides of the non-fixed ends of the two branch pipes 221 are bolted with inwardly inclined hooks 222. The bottom surface of the limiting plate 223 is bolted to the fixing plate 214. The branch pipes and limiting plates between adjacent bidirectional conveyor frames cooperate to vertically clamp and fix the LED packaging reel, while not affecting the oven body from any angle to bake and dehumidify the LED packaging reel.

[0023] The unloading assembly 23 includes a mounting base 231 and unloading plates 232. The mounting base 231 is bolted to the bottom surface of the furnace body 1, and the two unloading plates 232 are bolted to both sides of the mounting base 231. The top surface of the unloading plate 232 is constructed with an inverted V-shaped inclined surface. The inclined surface on the unloading plate cooperates with the bidirectional conveyor frame to unload the LED packaging reel and send it to the next workstation for processing by the unloading mechanism.

[0024] Example 2:

[0025] When two or more bidirectional conveyor frames 22 are fixedly connected to the fixed plate 214 by parallel equidistant bolts, two or more feeding mechanisms 3 and unloading mechanisms 4 are provided at the upper and lower front ends of the machine body 10, and two or more unloading components 23 are provided on the inner bottom surface of the furnace body 1 below the front end of the conveyor assembly 21.

[0026] In practical applications, this mechanism is located inside a tunnel furnace. The upper and lower ends of the front end of the conveying component are the input and output ends, respectively, both of which are connected to the external conveyor line. The bidirectional conveyor frame rotates upward at the front end to pick up the undried and dehumidified LED packaging reels from the external conveyor line and slides them onto the limiting plate for loading. At the same time, it abuts against the previous bidirectional conveyor frame to fix the LED packaging reels in place. When the rear end of the conveying component rotates downward, the LED packaging reels loaded in the limiting plate of the bidirectional conveyor frame slide into the hook of the previous bidirectional conveyor frame. The two abut against each other to fix the LED packaging reels in place and continue to be conveyed. When the bidirectional conveyor frame rotates upward at the lower front end of the conveying component, the bottom surface of the LED packaging reel slides into contact with the inclined surface of the top surface of the stripping plate, gradually rising from the hook and sliding down onto the external conveyor line, from where it is sent to the next workstation for processing.
